Title: Apparatus for gripping and lifting articles
Inventor: ORLOFF GEORGE
IPC: B25J13/02
Filed: 1961-07-21
Abstract: 955,005. Article gripping devices. MOLINS MACHINE CO. Ltd. July 20, 1962 [July 21, 1961], No. 26554/61. Heading B84. A mechanical handling apparatus, Fig. 1, has gripping jaws 1, 2 which have means 5 for detecting slipping of the load relative to the jaws. The jaws follow the movements of a controller 33 which comprises levers 41, 42 through which an operator inserts his first finger and thumb. In a first embodiment a ball 5, Fig. 2, bears against the object heing gripped and if the latter slips the ball 5 rotates and in so doing rotates a further ball 64 through a ball-bearing 65. These balls are held against the load by springs 53, 60. The ball 64 is made of magnetic material, has depressions filled with non-magnetic material, and is housed in a shell 63 of polytetrafluoroethylene. Rotation of the ball 64 is detected by an inductive pick-up 67. The signal from the pick-up is amplified and fed to electromagnets 82, Fig. 3, which cause styli 78, 79 to vibrate against the operator's finger and thumb so that he tightens his grip on the controller thus causing the jaws 1, 2 to grip harder and prevent the load slipping. The balls in the two jaws are off-set so that rotational slip can be detected even if the axis of rotation passes through one of the balls. Hydraulic bellows 74, 75 provide an indication to the operator of the force being exerted by the jaws 1, 2. The controller 33 may regulate either the pressure or the flow of hydraulic fluid to the jaw operating rams. The ball 64 may be made of conducting material and have the indentations filled with non-conducting material so that if a voltage is applied to its surface by two probes rotation causes a fluctuating signal to be produced. Alternatively a photoelectric cell may be used to detect rotation of a ball who's surface consists of alternating black and white areas. In a further embodiment, Fig. 4, each jaw has a tachogenerator 83 driven through gearing 85, 86 by a friction band 89 which passes round pulleys 88, 90 and bears against the load through an aperture 91. A friction drum instead of a band may be used. The bands or drums on opposite jaws have their axes at 90 degrees to each other so that slip can be detected in all directions. All the movements of the jaws 1, 2 may be controlled by a tape or punched card. Alternatively only the gripping movement may be automatically controlled in response to the slip signals.

Title: Improvements in and relating to insulating coatings on conductors
IPC: C25D13/00
Filed: 1952-10-23
Abstract: Aqueous dispersions suitable for use in the electrophoretic deposition on a conductor of adherent coatings comprising as main ingredients 80-90 per cent of polytetrafluorethylene and 10-20 per cent of an organopolysiloxane resin (see Group XXXVI) are prepared by mixing aqueous dispersions of the ingredients to give these proportions.  The polysiloxane resin emulsion may comprise an emulsion of methyl phenyl siloxane resin containing an average of about 1.6 total methyl and phenyl groups per silicon atom, the resin being dissolved in a solvent such as xylene or toluene and then emulsified with water; a silicone resin cure accelerator such as zinc octoate may be incorporated and as emulsifying agent there may be used a condensation product of polyethylene glycol with alkyl, aryl or alkyl and/aryl acids or alcohols, stearamineacetate, morpholine oleate, and sorbitan monolaurate alkylene derivatives.  The polytetrafluorethylene emulsion may contain other heat-resisting polymers such as polymerized monochlortrifluorethylene.  Insulating tapes may be made by depositing the resins on ribbon-shaped electrodes and then stripping off the deposits.  Specifications 542,655, 548,911 and 597,834 are referred to.
Patent GB-1429844-A (GB)
Title: Apparatus for sorting and stacking sheets
IPC: B65H29/24
Filed: 1973-06-05
Abstract: 1429844 Delivering sheets HOECHST AG 5 June 1973 [7 June 1972] 26737/73 Heading B8R Sheets are conveyed by an endless belt 1, comprising a plurality of spaced straps, over a plurality of pockets 7-13, being held in contact with the belt by air drawn between the straps into a suction box 6. At the top of each pocket 7-13 is a pivoted deflection flap 14-20 which when in the sloping position shown for 15, 16 deflects a sheet into the corresponding pocket. The flaps 14-20 are held in horizontal position when electromagnets 22-28 are energized. When a magnet is de-energized, the flap is still held in horizontal position by the suction, until the part of the belt above it is at least partially blocked by a sheet, when the flap falls into its sloping position by gravity. A further flap 21 is provided upstream of the flap 14, with a magnet 29. The flaps 14-21 actuate microswitches 30-37 when in sloping position, and each microswitch 30-36 when actuated de-energizes the magnet of the next flap upstream, while the switch 37 produces a short current surge through all the magnets. In operation, the flap of the furthest downstream pocket to be used in a run is manually moved to the sloping position and immobilized. For example, if three copies are to be made from each of a plurality of originals, the flap 16 is immobilized, de-energizing magnet 23, flap 15 remaining closed by suction force. The first copy 38 is deflected into the pocket 9, and as it blocks the belt over the flap 15 the latter falls open, so that the second copy 39 enters the pocket 8. The third copy 40 enters the pocket 7, at the same time causing the flap 21 to open, thus energizing all the electromagnets and closing all the flaps except the immobilized 16, all the magnets except 23 thus remaining energized, and the cycle being repeated, beginning with the first copy 41 from the second original entering the pocket 9. Air from a nozzle 44 cleans the sheets before they enter the pockets. Sheets not to be sorted are deflected by a plate 42 into a compartment 43. The assembly of pockets may be removed as a whole when a run is finished, and replaced by a similar, empty assembly.

Title: Store for waste material
IPC: G21F9/24
Filed: 1975-06-25
Abstract: 1492458 Disposal of radioactive waste KRAFTWERK UNION AG 25 June 1975 [10 July 1974] 27027/75 Heading G6R A store for radioactive waste material comprises walls defining a cavity, a plurality of containers within the cavity accommodating the waste material, and a water-insoluble material provided externally of the containers so as to prevent water contacting the containers and washing the waste material out of the store. Fig. 1 shows a salt mine which contains several cavities in the form of caverns 2, 3, 4 in the rock 1. The waste is transported in containers 15, arriving in shielded wagons 13, and being lowered from a winding tower 9 on to mine cars 16 by which they are carried to the entrances 18 of the caverns. The containers 15 are introduced at random into the caverns and, as shown in cavern 2, the gaps between the containers are filled with a sealing compound 17 which forms a water-insoluble covering around them. Alternatively, as in cavern 3, the wall of the cavern itself is lined with a layer 19 of waterinsoluble material. In cavern 4, the containers 15, in addition to the water-insoluble layer 19 on the inner wall of the cavern are surrounded by sealing compound 17 as in cavern 2. The waterinsoluble may be bitumen, concrete or other liquid, viscous or hardenable materials. The water-insoluble layer may thus be made entirely, or in part, of slag, lime sludge, rubble, &c. optionally in conjunction with binders or agents which promote the fluidity of the mass. Cement for example may be mixed with the above-mentioned industrial waste materials and with water to form a hardenable sealing compound. In alternative embodiments, the cavity lining may in addition to a concrete layer comprise a bitumen layer on the inside of the concrete layer (Fig. 3, not shown) or a concrete layer which is held down by anchors may be arranged on the inside of a bitumen layer (Fig. 4, not shown). As shown in Fig. 5, large containers 42 which have flat walls and are easy to stack may be used. A concrete base 43, together with sealing compound in a lateral gap 44, optionally maintained by spacers 45, forms the waterinsoluble lining on the outside of the containers 42. Gaps 47, 48 filled with sealing compound may also be formed by means of spacers 46 between each row of containers 42.

Filed: 1937-10-06
Abstract: 501,373. Electric control systems. GENERAL ELECTRIC CO., Ltd., and BARSDORF, L. W. Oct. 6, 1937, No. 27075. [Class 40 (i)] [Also in Group XX] Means under remote control for driving a wind vane to a desired indicating position when there is insufficient wind includes a normally disengaged friction clutch which is adapted to be engaged independently of the driving means. As shown, the vane shaft 11a carries a gearwheel 18 for driving a transmitter 20, a friction disc 17 and a freely rotatable worm-wheel 21. A second friction disc 29 is axially movable-on, but rotates with, the shaft 11a and is urged into contact with the wheel 21 by a spring 33. When in this position the vane may be rotated by energizing a motor 27 geared to the wheel 21. The friction clutch maintains the vane locked to the wheel 21 but permits it to respond to sudden squalls. To permit the vane to swing freely, a motor (not shown) is energized and rotates a cam 37. The latter rocks a lever engaging the lower end of an operating rod lying within the shaft 11a and connected at the top to the friction disc 29. The disc 29 is thus raised and the shaft 11a allowed to swing independently of the wheel 21. Change-over switches are provided to open the circuit of the motor driving the cam 37 upon completion of each adjustment of the friction disc 29.

Title: Improvements in or relating to steam distillation
IPC: B01D3/38
Filed: 1950-11-06
Abstract: <PICT:0679430/III/1> <PICT:0679430/III/2> In the distillation, e.g. of petroleum oils, in a steam stripped column operating under vacuum and comprising a reflux zone and an absorption zone above the reflux zone, part of the liquid is withdrawn from the reflux zone, cooled in a heat-exchanger and the major part returned to the reflux zone and into direct contact with the vapours therein to condense the heavier components of the vapours, the remainder being further cooled and returned to the absorption zone to condense the lighter components of the residual vapours, a liquid product and substantially product-free steam being withdrawn from the absorption zone.  Large vapour condensers for the product are thus avoided.  In Fig. 1 liquid is taken off a tray 18a, forced by pump 22 through heat exchanger 24 and the major part returned by valved line 26 to upper tray 18b. Uncondensed vapours and steam pass to the absorption zone formed by plates 30, 30a, and the remainder of the liquid taken from tray 18a is further cooled in heat exchanger 36 and returned to tray 30. Product is taken by line 44 from a tray on plate 30a.  Steam passes overhead and is condensed at 38.  The usual vacuum jet 40 and barometric condenser 42 are provided.  The column may be controlled by automatic regulation of a valve 45 in product line 44 in response to the temperature at an intermediate point in the column, surplus liquid from tray 30a being returned by line 31 to tray 18b. Alternatively the valve 45 may be replaced by a flow control valve giving a constant output.  In the modification (Fig. 2) the product from tray 30a goes to an accumulator 46 from which it may be pumped to product line 35 or, in part, by valved line 35a and cooler 36 to tray 30.  A valved line 37 replaces line 31. Lines 37 and 35a may be used separately or together to control the temperature at the top of the column and the composition of the product.  Crude oil may be introduced to the columns at 12, and one or more sidestreams may be removed from the columns, steam and vapours from the sidestream strippers being returned to the columns through one or more lines 16.
